Those that have mounted the z28 wheels were running factory street alignment, the issues arise when you start to use more camber, as it reduces strut clearance. I'm at -2.6* and the wheels needed 5mm spacer in order to clear. You'd have to do the math to figure out what a tenth of a degree equals in mm movement at the rim edge. I would assume 2* would still need some sort of spacer.

Just to give an update, I did manage to put a 5mm spacer on to actually check and the wheel clears fine. It's close, probably about 1.5mm from the strut, but it will clear. There shouldn't be any deflection in the rim...

Did you get a chance to weigh them?

Sorry I did, but I can try to get a weight at some point with tires on.

keep us posted man

Since this question will pop up a million or so times in the next year, and what the wheels specs are, can the mods sticky this?

Have received one front and two rear A1Z wheels in. Doesn't really matter since the G3R's are not in yet either.

On my own shipping scale, accuracy seems decent but is unknown, the front weighs 26.8# and rear 27.1#. Similar to my SS 1LE wheels as far as fronts not much lighter than rears since it is just the thin 1" wider barrel in the rear for the most part. These are about 3# each lighter than the SS 1LE wheels.

Also, on my same scale, the G3's weigh 31.8# for the 305 and 29.5# for the 285/30/20. I will weigh the 305 & 325/30/19 G3R's when they come in.

Hmm they're still heavy almost exactly like the previous Gen Z28 wheels :/ Thanks for the information

Not bad weight or cost for a performance validated (radial fatigue, runout, etc.) / true DOT wheel. Of course, not as light as a true race wheel...

for the reference, CCW Corsair monoblock forged wheels with 3000 lbs load rating weigh around 20-21 lbs (and below 20 lbs for 18" setup) and they're not much more expensive than the OEMs. (I've seen them go as low as $3000-3400) 6-7 lbs of rotational mass is huge.

I wanted to post a quick update after an event that I was able to do. Under full load the tire will rub the inside of the fender lip. It appears to barely rub, as I had no idea it was doing this until I pulled the wheel off to do brakes. I just happened to grab the fender lip and felt, then saw, some rub marks. This was after a session on track (Laguna Seca), I don't believe you can get the same amount of load on the street. So to restate, the 19x11 +11 w/ 5mm spacer will rub the outside fender lip. I don't suspect any issues once the 5mm spacer is no longer used (Moreno camber plates, or less knuckle-camber).

Zl1 1le come with nitto tires? Id still like the look of the ss1le more thought

Thanks Sean. Which tires were you on?
